Thanks fellas but you are overthinking this. I am talking ONLY about the metal key that will ONLY open the DOOR. No chips or electronics of any kind. This is the slim little guy that is stored in the electronic key case that you use to start the car. By having a spare of this you can secure it to the bumper or wherever so you can at least gain access to the inside of the car where you can perhaps hide the electronic key or at least get out of the rain or snow until someone rescues you.
